Published Wildfire smoke downwind affects health, wealth, mortality
(via sciencedaily.com) Original source Smoke particulates from wildfires could cause between 4,000 and 9,000 premature deaths and cost between $36 to $82 billion per year in the United States, according to new research.
Published Clean, sustainable fuels made 'from thin air' and plastic waste
(via sciencedaily.com) Original source Researchers have demonstrated how carbon dioxide can be captured from industrial processes -- or even directly from the air -- and transformed into clean, sustainable fuels using just the energy from the Sun.
Published Hydrogen battery: Storing hydrogen in coal may help power clean energy economy
(via sciencedaily.com) Original source The quest to develop hydrogen as a clean energy source that could curb our dependence on fossil fuels may lead to an unexpected place -- coal. Scientists have found that coal may represent a potential way to store hydrogen gas, much like batteries store energy for future use, addressing a major hurdle in developing a clean energy supply chain.
Published Researchers examine cooling power plants with brackish groundwater
(via sciencedaily.com) Original source Nontraditional water sources can be deployed to help cope with climate-induced water risks and tackle the increasing water demand for decarbonization of fossil fuel-fired power plants, but that could increase the cost of electricity generation by 8 percent to 10 percent.
Published Demystifying vortex rings in nuclear fusion, supernovae
(via sciencedaily.com) Original source Better understanding the formation of swirling, ring-shaped disturbances -- known as vortex rings -- could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to becoming a viable energy source. A mathematical model linking these vortices with more pedestrian types, like smoke rings, could help engineers control their behavior in power generation and more.
Published Wildfire spread risk increases where trees, shrubs replace grasses
(via sciencedaily.com) Original source A new study found that as woody plants like shrubs and trees replace herbaceous plants like grasses, spot fires can occur farther away from the original fire perimeter.
Published Driving on sunshine: Clean, usable liquid fuels made from solar power
(via sciencedaily.com) Original source Researchers have developed a solar-powered technology that converts carbon dioxide and water into liquid fuels that can be added directly to a car's engine as drop-in fuel.
Published Watch these cells rapidly create protrusions for exploration and movement
(via sciencedaily.com) Original source In order to move, cells must be able to rapidly change shape. A team of researchers show that cells achieve this by storing extra 'skin' in folds and bumps on their surface. This cell surface excess can be rapidly deployed to cover temporary protrusions and then folded away for next time.
Published African smoke over the Amazon
(via sciencedaily.com) Original source Up to two-thirds of the soot above the central Amazon rainforest originates in Africa. Researchers differentiate soot particles using their relative properties and attribute them to their respective points of origin. They found that bush fires and burning savannah in the north and south of Africa make a substantial contribution to air pollution in the central Amazon all year round, thereby playing an important role in the earth radiation budget and water cycle. This is caused by the efficient transatlantic transport of particles through the atmosphere.
Published 'Improved' cookstoves emit more ultrafine particles than conventional stoves
(via sciencedaily.com) Original source Improved cookstoves, which are widely used for cooking in developing countries, produce twice as many harmful ultrafine air pollution particles (PM0.1) as conventional stoves, according to a new study.
Published Scientists discover fire records embedded within sand dunes
(via sciencedaily.com) Original source A new study shows that sand dunes can serve as repositories of fire history and aid in expanding scientific understanding of fire regimes around the world.
Published Unlocking the power of photosynthesis for clean energy production
(via sciencedaily.com) Original source Researchers are embarking on a groundbreaking project to mimic the natural process of photosynthesis using bacteria to deliver electrons to a nanocrystal semiconductor photocatalyst. By leveraging the unique properties of microorganisms and nanomaterials, the system has the potential to replace current approaches that derive hydrogen from fossil fuels, revolutionizing the way hydrogen fuel is produced and unlocking a powerful source of renewable energy.
Published CO2 recycling: What is the role of the electrolyte?
(via sciencedaily.com) Original source The greenhouse gas carbon dioxide can be converted into useful hydrocarbons by electrolysis. The design of the electrolysis cell is crucial in this process. The so-called zero-gap cell is particularly suitable for industrial processes. But there are still problems: The cathodes clog up quickly.
Published Methane from megafires: More spew than we knew
(via sciencedaily.com) Original source Using a new detection method, scientists found a massive amount of methane, a super-potent greenhouse gas, coming from wildfires -- a source not currently being accounted for by California state air quality managers.
Published Wildfires and animal biodiversity
(via sciencedaily.com) Original source Wildfires. Many see them as purely destructive forces, disasters that blaze through a landscape, charring everything in their paths. But a new study reminds us that wildfires are also generative forces, spurring biodiversity in their wakes.
Published Shutting down nuclear power could increase air pollution
(via sciencedaily.com) Original source A new study shows that if U.S. nuclear power plants are retired, the burning of coal, oil, and natural gas to fill the energy gap could cause more than 5,000 premature deaths.
Published Moving towards 3 degrees of warming -- the phasing out of coal is too slow
(via sciencedaily.com) Original source The use of coal power is not decreasing fast enough. The Paris Agreement's target of a maximum of 2 degrees of warming appear to be missed, and the world is moving towards a temperature increase of 2.5 -- 3 degrees. At the same time it is feasible to avoid higher warming.
Published Sailing cargo ships can benefit from new aerodynamic tech
(via sciencedaily.com) Original source A research team has demonstrated a unique method that reduces the aerodynamic resistance of ships by 7.5 per cent. This opens the way for large cargo ships borne across the oceans by wind alone, as wind-powered ships are more affected by aerodynamic drag than fossil-fueled ones.
Published Eco-efficient cement could pave the way to a greener future
(via sciencedaily.com) Scientists develop process to remove toxic heavy metals from coal fly ash, making for greener, stronger concrete.
Published Team uses natural catalysts to develop low-cost way of producing green hydrogen
(via sciencedaily.com) Researchers have developed a practical way to produce green hydrogen using sustainable catalysts and say their work is a major step towards production simpler, more affordable and more scalable.
